底片

The act of exposing sensitized photographic film or plate.

感光胶片或底片的曝光的行为。

The main principle of this technique is to control sensitization time of photographic plate by light impulse instead of shutter.

高速频闪摄影技术的主要特点在于：用光脉冲代替相机快门，以控制底片的感光；在光脉冲时间非常短(本文最小光脉冲宽度可达8μs，其技术指标代表目前国内的最高水平)的情况下，达到对高速运动的流体"冻结"而拍照、观察的目的。

Pierre:You mean then that there is something about that rock that gives off rays of its own-rays powerful enough to go through black paper and affect this photographic plate.

皮埃尔：你是说这块矿石有某种特性，能够自己发光，而且光线很强，能够穿透黑色的纸，并对底片产生作用。例2（玛丽萌发深入研究放射性的念头

In photographic photometry we use photographic plates of a certain region of the sky to determine the coordinates of the stars.

在照相测光中，我们利用所拍摄的天空某一区域的照相底片来测定恒星的坐标。

Utilizing the crosslinking behaviors of photopolymer under exposure to the light, the image on a photonegative film can transferred to a gelatin film, and then form on a electrochromic device by electrodeposition.

利用感光性高分子曝光产生交链的特性，可将照相底片的影像转变到凝胶膜上，再经电镀可将此影像转变到电致色变装置上。

They've selected their subjects carefully and framed their views of them precisely, in order to give their pictures the look of "art." Later in the 19th century,"pictorialist" photographers used soft focus, toothy paper, sepia tones, multiple negatives and even scratching back into the image as ways of getting photographs to look more like paintings.

他们会仔细地挑选各种主题，在作品中准确地表达自己的观点，让作品看起来更富有艺术内涵。19世纪末期，画意摄影师利用柔焦，齿边相纸，红褐色调，多底合成，甚至划花底片等方式让照片看起来更像绘画作品。

I know that you can't fake a Polaroid. There's no negative.

我只知道你不能对速拍相机做手脚因为没有底片

Then, the active wheel pull the whole system to move forward or backward on the preconcerted tramroad.

该系统可以在有大量臭氧存在的环境下自动夹取、运送底片，不需要等到臭氧从检测室排除，所以大大地提高了工作效率。

You can get good prints if you send them out.

如果你把底片送出去印，你就可以得到好的照片。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
